HIGH-SENSITIVITY SURFACE PLASMON RESONANCE SENSOR, SURFACE PLASMON RESONANCE SENSOR CHIP, AND METHOD FOR MANUFACTURING A SURFACE PLASMON RESONANCE SENSOR DEVICE

摘要

According to one embodiment of the present invention, a surface plasmon resonance sensor comprises: a metal thin film; a material pattern formed on the metal thin film for generating an exciter field by means of localized surface plasmon resonance; a mask layer for partially shielding the material pattern and the metal thin film so as to confine a bonding region or reaction region of a sample material to a hotspot that is a point at which a proximate exciter field, which is locally amplified via localized surface plasmon resonance, is formed; a light source for supplying light incident to the metal thin film; and a light collector for detecting light reflected from the metal thin film.
